Origin:
Magnetic check valve manufacturers say that a check valve refers to a valve whose opening and closing parts are circular discs and act by its own weight and medium pressure to block the backflow of the medium. Common check valves are as follows.
1. Lifting check valve: According to the magnetic check valve manufacturer, there are two types of lifting check valve: vertical and horizontal. The valve body shape of the lift check valve is the same as that of the globe valve, so its fluid resistance is larger. The disc slides along the vertical centerline of the valve body. When the medium flows downstream, the valve flap is opened by the thrust of the medium, and when the medium stops flowing, the valve flap falls on the valve seat by self-sagging.
2. Swing check valve: According to the magnetic check valve manufacturer, the disc of the swing check valve is disc-shaped and rotates around the shaft of the valve seat channel. Because the channel in the valve is streamlined, the flow resistance is higher than that of the lift check valve. Small, suitable for small and medium-diameter, low-pressure large-diameter pipelines. The sealing performance is not as good as that of the lift type.
3. Butterfly check valve: Magnetic check valve manufacturers said that the structure of butterfly check valve is similar to that of butterfly valve. Its structure is simple, the flow resistance is small, and the water hammer pressure is also small. A check valve in which the disc rotates around a pin in the seat. The disc check valve has a simple structure and can only be installed on the horizontal pipeline, and the sealing performance is poor.
4. Diaphragm check valve: Magnetic check valve manufacturers said that diaphragm check valves have various structural forms, all of which use diaphragms as opening and closing parts. Because of their good waterproof hammer performance, simple structure and low cost, they have developed in recent years. faster. However, the operating temperature and pressure of the diaphragm check valve are limited by the diaphragm material.
